SIEPEL EMC Absorber for Ferrite Chamber 1 - 40 GHZ

HY & HYT are high performances electromagnetic absorbers to be installed over ferrite tiles. They are used in EMC anechoic chambers to get broadband reflectivity performances.

These absorbers are dedicated to new chambers or within the framework of retrofit / upgrade.


SIEPEL has developed a specially matched EMC pyramidal absorber which provides high performances over the frequency range 1 GHz – 40 GHz. Its broadband features make it ideal to meet the specifications of:
  • EMI standards, such as CISPR 16-1-4, CISPR 25, ISO 11452-2, EN 50147-2, EN 55022, ANSI C63.4 and similar standards
  • EMS standards, such as EN / IEC 61000-4-3
  • MIL-STD and DO applications.

These reflectivity performances values are outstanding and guaranteed for 20 years. They are based on extensive experience in electromagnetic absorbers manufacturing. Their reflectivity performances are factory checked, using cutting-edge broadband equipment (14 m long coaxial line with a 1.83 x 1.83 m section, fully anechoic chamber with optimised design, VNA). In addition, we offer our customers to perform reflectivity measurements in our factory with SIEPEL engineers.

We can also provide a combined hybrid solution, based on our experience and simulation capabilities. Refer to our datasheet HYBRID PYRAMIDAL ABSORBER HY & HYT for more information.
